Benchmark Comparison Question w/ Asus 980ti

[JudeSaint]

So i ran the Firestrike (demo version) Benchmark with my new 980 TI Strix.

Here is my Score


My question is this .... Is something bottle necking my system or am i doing something wrong? Here is another link of a similar system.
My Core clock and memory are both substantially higher than his.
His CPU and the Bus speed of his GPU are better/higher than mine.

His score is just about Double mine.

Honestly have no idea what's up with that result. His 980Ti is also listed as having only 1GB of RAM. My result is close to yours and seems more in line with what you could expect from a slightly higher end system, 15013 with a 4790K + Titan X. My GPU score was only 18231 compared to your 18368, but it's also from an older driver (350.12)
